- The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, and also assists in the removal of metabolic wastes.The heart is located in the middle compartment of the mediastinum in the chest.he heart functions as a pump in the circulatory system to provide a continuous circulation of blood throughout the body. This circulation consists of the systemic circulation to and from the body and the pulmonary circulation to and from the lungs.

- Cardiac muscles are the muscles of the heart. They are self-contracting, autonomically regulated and must continue to contract in rythmic fashion for the whole life of the organism.Hence they have special features. The cells are Y shaped and are shorter and wider than skeletal muscle cells.he arrangement of actin and myosin is similar to skeletal striated muscle. Some of the cardiac muscle cells are auto-rhythmic, i.e they contract even in the absence of neuronal innervation (known as pacemaker cells).

Cardiac muscle Cardiac muscle (heart muscle) is one of the three major types of muscle, the others being skeletal and smooth muscle. It is an involuntary, striated muscle that is found in the walls of the heart. This muscle tissue is known as myocardium, and forms a thick middle layer between the outer layer of the heart wall (the epicardium) and the inner layer (the endocardium).

Heart The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, and also assists in the removal of metabolic wastes.The heart is located in the middle compartment of the mediastinum in the chest.ardiomyocytes, like all other cells, need to be supplied with oxygen, nutrients and a way of removing metabolic wastes. This is achieved by the coronary circulation. The coronary circulation cycles in peaks and troughs correlating to the heart muscle's relaxation or contraction.

How Long Do Bees Live? Queen Honey Bees: All being well, a honey bee queen could live for 3 to 4 years, as long as she is free from disease. This is much longer than bumblebee queens or the solitary bee species. However, a queen that produces few eggs may not be favoured by the colony.In such a case, a new queen will be produced, and the old queen replaced.ll being well, a honey bee queen could live for 3 to 4 years, as long as she is free from disease.

How to Self-Publish an Adult Coloring Book The first step in creating your adult coloring book is to pick a theme. You will not be able to get by with a bunch of random drawings. Today’s coloring books are themed. For example, Dover Publishing specializes in educational coloring books, with lined sketches of “Georgia Wildflowers” and “Ancient Egypt.”.

Muscle The cardiac muscle is the muscle in the heart. When this muscle contracts (makes itself smaller) it pushes blood through the circulatory system. The cardiac muscle is not voluntary. Animals do not choose for their heart to contract. The smooth muscles are the other muscles in the body that are involuntary.

Anatomy & Physiology - Body Systems Heart. The function of the heart is to pump blood around the body. The heart is a hollow, muscular organ divided by a vertical wall called the septum. These two chambers are further divided into the thin walled atrium above, and a thick walled ventricle below, making four chambers.

Heart The functions of the heart are to pump oxygenated blood around the body, and to deliver deoxygenated blood and waste products (carbon dioxide) to the lungs. The heart consists of four chambers, each separated by valves that only permit blood to flow in one direction.

The Cardiovascular System: Mechanics and Dynamics The heart is a specialized organ, and the only one in the body made of cardiac muscle. Heart cells are called cardiomyocytes and make up muscle fibers that conduct electrical …impulses. The function of the heart, which is to keep blood flowing throughout the body, is controlled by involuntary areas of the brain.

- Like other muscles, it needs oxygen and nutrients to function. The heart receives its oxygen and nutrients from blood pumped from a large blood vessel called the aorta, through smaller blood vessels called arteries (coronary arteries), then through even smaller vessels called arterioles and capillaries.ike other muscles, it needs oxygen and nutrients to function.

What is the function of the heart? The heart's main function is to pump blood, making it the  functional core of the circulatory system. Incoming,  deoxygenated blood is pumped through the right side of the h … eart  and to the lungs, where the carbon dioxide is replaced with fresh  oxygen.

Epithelial, Connective, Muscular, and Nervous Tissue Cardiac muscles are found in the heart and cause the body to take in oxygen. If muscle tissue were not located in the heart than the body will not be able to properly function and we will be dead. The main function of the Nervous Tissue is to generate and transmit nerve impulses to and from body organs.

Heart The heart is a muscular organ that pumps blood throughout the body, with a rhythm determined by a group of pacemaking cells in the sinoatrial node. These generate a current that causes contraction of the heart, traveling through the atrioventricular node and along the conduction system of the heart.

Why is the heart the most important muscle? The heart is the most important muscle of the body because it is the organ that pumps the blood throughout the body to carry out oxygen and nutrients, and helps collect and el … iminate carbon dioxide and other wastes from the body.1 person found this useful.or the cells to respire they need oxygen and glucose as substrates. The waste products after the reaction is carbon dioxide, as human body is large it needs a pump to circulate all this oxygen to all the cells and dispose the waste co2 to the lungs. So, heart muscle is important muscle in the whole human body.

Heart Structure - Anatomy & Physiology The skeleton performs several functions: 1  It serves as a point of attachment for the heart valves. 2  The cardiac muscle bundles insert onto the fibrous skeleton. 3  It prevents the valves from overstretching as blood passes through them.

It is made up of cardiac muscle and is the only place in the body where such muscle is found. All the other muscles in the body are composed of either skeletal muscle or smooth muscle. The most muscular part of the heart is its middle layer, called the myocardium, which is mainly responsible for its contractions.

Human Physiology/Print Version How does it keep busy? What does it look like? Let's find out. Working That Muscle. Your heart is really a muscle. It's located a little to the left of the middle of your chest, and it's about the size of your fist. There are lots of muscles all over your body — in your arms, in your legs, in your back, even in your behind. But the heart muscle is special because of what it does. The heart sends blood around your body. The blood provides your body with the oxygen and nutrients it needs. It also carries away waste. Your heart is sort of like a pump, or two pumps in one. The right side of your heart receives blood from the body and pumps it to the lungs. The left side of the heart does the exact opposite: It receives blood from the lungs and pumps it out to the body.
