angiotensin II – protein produced by the enzymatic action of ACE on inactive angiotensin I; actively leads to vasoconstriction and stimulates aldosterone launch through the adrenal cortex.
bicuspid valve – (also, mitral valve or still left atrioventricular valve) valve located among the left atrium and ventricle; is made of two flaps of tissue.
basilic vein – superficial vein with the arm that occurs through the palmar venous arches, intersects While using the median cubital vein, parallels the ulnar vein, and continues in the higher arm; along with the brachial vein, it brings about the axillary vein.
cleavage – type of mitotic cell division wherein the mobile divides but the total volume remains unchanged; this process serves to supply smaller and scaled-down cells.
Human Physiology (physio = “mother nature”; -logy = “research”) research the “nature” with the human body, character while in the sense of how constructions at distinct ranges function. Physiology concentrates on functionality
coeliac trunk – (also, coeliac artery) big branch of the abdominal aorta; offers increase to the remaining gastric artery, the splenic artery, along with the prevalent hepatic artery that forms the hepatic artery to the liver, the appropriate gastric artery to your belly, plus the cystic artery towards the gall bladder.
arrector pili – easy muscle that's activated in response to external stimuli that pull on hair follicles and make click here the hair “rise up”.
cilia – little appendage on certain cells fashioned by microtubules and modified for motion of supplies over the mobile floor.
atrioventricular bundle – (also, bundle of His) team of specialised myocardial conductile cells that transmit the impulse through the AV node with the interventricular septum; form the left and suitable atrioventricular bundle branches.
anterior inferior iliac spine – little, bony projection Situated to the anterior margin on the ilium, underneath the anterior excellent iliac spine.
continuous capillary – most popular sort of capillary, present in pretty much all tissues besides epithelia and cartilage; consists of very small gaps from the endothelial lining that permit exchange.
When a person considers the relation of such subdivisions in click here the skeleton for the soft portions of the human body—including the anxious system, the digestive process, the respiratory method, the cardiovascular process, plus the voluntary muscles in the muscle mass process—it is obvious which the features in the skeleton are of a few differing types: aid, protection, and movement.
connective tissue – kind of tissue that serves to carry in position, connect, and combine the body’s organs and programs.
anterior corticospinal tract – division from the corticospinal pathway that travels in the ventral (anterior) column in the spinal twine and controls axial musculature in the medial motor neurons inside the ventral (anterior) horn.
