anastomosis – (plural = anastomoses) area where by vessels unite to permit blood to circulate even when there might be partial blockage in One more department.

corpus spongiosum – (plural = corpora cavernosa) column of erectile tissue inside the penis that fills with blood for the duration of an erection and surrounds the penile urethra on the ventral percentage of the penis.

bronchoconstriction – minimize in the dimensions on the bronchiole because of contraction on the muscular wall.

central canal – longitudinal channel within the centre of each and every osteon; has blood vessels, nerves, and lymphatic vessels; also referred to as the Haversian canal.

aorta – largest artery within the body, originating within the left ventricle and descending on the abdominal location the place it bifurcates in the frequent iliac arteries at the extent of your fourth lumbar vertebra; arteries originating from the aorta distribute blood to nearly all tissues from the body.

atrial reflex – (also, known as Bainbridge reflex) autonomic reflex that responds to stretch receptors inside the atria that mail impulses on the cardioaccelerator location to raise HR when venous flow to the atria will increase.

The main law of thermodynamics retains that Vitality can neither be established nor wrecked—it can only alter sort. Your fundamental perform being an organism is usually to eat (ingest) Vitality and molecules inside the foods you try to eat, change some of it into fuel for movement, sustain your body capabilities, and Make and manage your body constructions. There's two different types of reactions that carry out this: anabolism and catabolism.

cytoskeleton – “skeleton” of the cell; fashioned by rod-like proteins that guidance the cell’s condition and provide, between other capabilities, locomotive skills.

anchoring junction – mechanically attaches adjacent cells to one another here or into the basement membrane.

autorhythmicity – ability of cardiac muscle mass to initiate its individual electrical impulse that triggers the mechanical contraction that pumps blood at a hard and fast tempo without anxious or endocrine control.

blood colloidal osmotic strain (BCOP) – stress exerted by colloids suspended in blood inside a vessel; a Main determinant will website be the presence of plasma proteins.

corneal reflex – protective response to stimulation with the cornea triggering contraction of your orbicularis oculi muscle mass causing blinking of the attention.

anatomical lifeless House – air space existing during the airway that under no circumstances reaches the alveoli and for that reason in no way participates in fuel Trade.

anterior corticospinal tract – division in the corticospinal pathway that travels from the ventral (anterior) column on the spinal cord and controls axial musculature through the medial motor neurons during the ventral (anterior) horn.
