Heart and Heart Valves With reference to the anterior thoracic wall, Eycleshymer and Schoemaker found the apex of the heart at the level of the fifth intercostal space in the mamillary line. According to Joessel, Schultze, and others, the apex lies at the level of the fifth intercostal space midway between the parasternal and mamillary lines.

Drug delivery to the central nervous system: a review. These areas are adjacent to the ventricles of the brain and are termed the circumventricular organs (CVOs). The CVOs include the choroid plexus, the median eminence, neurohypophysis, pineal gland, organum vasculosum of the lamina terminalis, subfornical organ, subcommisaral organ and the area postrema.

- Information from these sensors is conveyed along nerves to the respiratory center in the brain stem. The respiratory center is situated in the reticular formation and other parts of the brainstem, and consists of 4 interconnected and interacting components: Inspiratory center - reticular formation, medulla oblongata.

Systems of Gas Exchange It consists of the nasopharynx, larynx, trachea, bronchi, bronchioles and terminal bronchioles. (We omit the nasopharynx and larynx in this block.) The respiratory portion serves to rid the body of carbon dioxide and pick up oxygen. It consists of respiratory bronchioles, alveolar ducts and alveolar sacs.

"""Interrelationship Between The Integumentary System And Other Body Systems"" Essays and Research Papers" RESPIRATORY SYSTEM. The complex of organs and tissue which are necessary to exchange blood carbon dioxide (CO 2) with air oxygen (O 2) is called the respiratory system. It consists of. structures, which function as ducts, and which together are called the conductive portion of the respiratory system structures which form the respiratory portion of the respiratory system, in which the exchange of CO 2 and O 2 is occurring and

Concept 3 Review A Closer Look: Cardiac Muscle Cells. Cardiac muscle cells are rectangular shaped cells connected by regions called intercalated discs. Intercalated discs contain gap junctions and desmosomes. The gap junctions, which are protein-lined tunnels, allow direct transmission of the depolarizing current from cell to cell, across the chambers of the heart, so that the cells contract in unison. Because of the way these gap junctions function, the cardiac muscle cells are said to be electrically coupled. The desmosomes hold the cardiac muscle cells together during contraction, induced by the sliding of the cardiac myofibrils.

Cardiovascular System Anatomy Cardiovascular System Anatomy The Heart. The heart is a muscular pumping organ located medial to the lungs along the body’s midline in the thoracic region. The bottom tip of the heart, known as its apex, is turned to the left, so that about 2/3 of the heart is located on the body’s left side with the other 1/3 on right.

- The circulatory system has a close interrelationship with the respiratory system. The main organ of the respiratory system is the lungs. The diaphragm is a muscle located underneath the heart and lungs that contracts to pull air into the lungs and relaxes to force air out of the lungs.When the air enters the lungs, it travels through the bronchi to tiny air sacs called alveoli.irculatory System. The circulatory system consists of the heart, blood, and blood vessels. There are three types of blood vessels: arteries, veins and capillaries. The heart is an organ made of cardiac muscle and it acts like a pump.

Cardiac skeleton The cardiac skeleton separates and partitions the atria (the smaller, upper two chambers) from the ventricles (the larger, lower two chambers). This is important because it forms the primary channel that electrical energy follows from the top to the bottom of the heart.he cardiac skeleton consists of four bands of dense connective tissue, as collagen, that encircle the bases of the pulmonary trunk, aorta, and heart valves.

- The cardiorespiratory system consists of the heart, the. blood vessels, and the respiratory system ( Figure 3.1 ). The cardiorespiratory system transports oxygen, nutri-. ents, and other key substances to the organs and tissues. that need them; it also carries waste products to where. they can be used or expelled. The Hear t The heart is a four-chambered, ﬁ st-sized. muscle located just beneath the sternum (breastbone).

Unit  IV â The Thoracic Cage/ Respiration & Breathing The thoracic cavity contains the heart, the lungs, and some abdominal organs. The thoracic cage provides attachments for muscles of the neck, thorax, upper limbs, abdomen, and back. The thorax moves up and down to allow breathing, so it is one of the most dynamic regions of the body.

What are Bronchioles Respiratory Bronchioles. The final division of bronchioles, these end in 2-11 alveolar ducts [7, 8], surrounded by the proteins elastin and collagen, and smooth muscles, each leading into an alveolar sac. These sacs contain multiple alveoli, encircled by pulmonary system blood vessels [9].

Anatomy Of The Respiratory System 8. The last component of the respiratory system is a muscle structure known as the muscles of respiration. These muscles surround the lungs and allow the inhalation and exhalation of air. The main muscle in this system is known as the diaphragm, a thin sheet of muscle that constitutes the bottom of the thorax.

What is a respiratory control center? exists and is an alternate of . Respiratory control centers are located in the medulla and the pons. In the medulla the ventral respiratory group contains rhythm generators whose output drives respiration. Also in the medulla, the neurons of the dorsal respiratory group integrate peripheral sensory input and modify the rhythms generated by the VRG.
