Human Physiology/Print Version The heart is a hollow muscular organ. The heart is a hollow muscular organ located in the center of the chest. The right and left heart each has an upper chamber (atrium which collects blood and the lower chamber (ventricle) that draws blood.

Muscular System: Facts, Functions & Diseases Found only in the heart, cardiac muscle is an involuntary muscle responsible for pumping blood throughout the body, according to The Merck Manual. The heart's natural pacemaker is made of cardiac muscle that signals other cardiac muscles to contract.

T or F? Skeletal muslces assist movement of the blood and help maintain body temp? The skeletal-muscle pump. The skeletal-muscle pump is a collection of skeletal muscles that aid the heart in the circulation of blood. It is especially important in increasing venous return to the heart, but may also play a role in arterial blood flow.

- Open circulatory systems (evolved in insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.

THE CIRCULATORY SYSTEM Vertebrate Cardiovascular System | Back to Top. The vertebrate cardiovascular system includes a heart, which is a muscular pump that contracts to propel blood out to the body through arteries, and a series of blood vessels. The upper chamber of the heart, the atrium (pl. atria), is where the blood enters the 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.n a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium.

The Heart and Blood Vessels The heart is a muscular pump that pushes blood through blood vessels around the body. Essential to life, the heart beats continuously, pumping the equivalent of more than 14,000 litres of blood every day. Blood vessels form the living system of tubes that carry blood both to and from the heart.roups of capillaries within a tissue reunite to form small veins called venules. Venules collect blood from capillaries and drain into veins. Veins are the blood vessels that carry blood back to the heart. They may contain valves which stop blood flowing away from the heart.

What does a heart look like?  [ edit] The heart is the strongest muscle in the body. The heart is a pump that pumps blood to different organs of the body. Blood is the medium that carries gases, liquids, nutrients, and waste all over the body.

What controls your blood pressure? Your heart is an organ that is mostly muscle tissue. It is a pump. In very simple terms its job is to receive incoming blood from the body that is low in oxygen and pump it to the lungs. As it passes through the lungs the blood gets rid of carbon dioxide and picks up oxygen.

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.

- Your heart is a muscular organ that pumps blood to your body. Your heart is at the center of your circulatory system.This system consists of a network of blood vessels, such as arteries, veins, and capillaries. These blood vessels carry blood to and from all areas of your body.our heart is vital to your health and nearly everything that goes on in your body. Without the heart's pumping action, blood can't move throughout your body. Your blood carries the oxygen and nutrients that your organs need to work well.

High Blood Pressure and the Heart As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system. The vessels are elastic, muscular tubes that carry blood to every part of the body. Blood is essential.he heart is an amazing organ. It pumps oxygen and nutrient-rich blood throughout the body to sustain life. This fist-sized powerhouse beats (expands and contracts) 100,000 times per day, pumping five or six quarts of blood each minute, or about 2,000 gallons per day.

Heart Heart Facts. The heart is a strong and muscular organ that is about the size of a fist in adults. It pumps blood throughout the body and is located behind the breastbone between the lungs. Deoxygenated blood flows from the heart to the lungs where it gives up carbon dioxide and is freshly oxygenated.

coeur heart. Hollow muscular organ that receives blood from veins and propels it into the arteries. In mammals, divided by a musculomembranous septum into two halves-right or venous and left or arterial-each of which consists of a receiving chamber (atrium) and an ejecting chamber (ventricle).

Muscular System The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system. The heart has four chambers: 1  The right atrium receives blood from the veins and pumps it to the right ventricle.  The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen.

- In skeletal muscle, the contraction allows the bone to move, thereby allowing your body to move. In the heart, the cardiac muscle pumps the blood into the arteries. The smooth muscles in blood vessels are used to pump blood in one direction (in veins, which is in low pressure, there are valves which prevents backflow).

Physiology Systole. The contraction of the cardiac muscle tissue in the ventricles is called systole. When the ventricles contract, they force the blood from their chambers into the arteries leaving the heart. The left ventricle empties into the aorta and the right ventricle into the pulmonary artery.he atrium then delivers blood to the powerful lower chamber, called a ventricle, which pumps blood away from the heart through powerful, rhythmic contractions. The human heart is actually two pumps in one. The right side receives oxygen-poor blood from the various regions of the body and delivers it to the lungs.
