To review:
Match the term collaterals with the most closely related descriptions given below:
deliver blood to the head
transport blood to the body’s skeletal muscles and internal organs
arteries whose smooth muscles do not contract
stationary blood clot
network of capillaries
arteries that supply a capillary network
supply blood to the upper limbs
small air sacs
supply blood to the lower limbs
collect blood from the kidneys
Introduction:
Arteries can be defined as the blood vessels that carry oxygenated blood, the only exception being the pulmonary artery. The arterioles and venules together form the capillary bed, through which the blood flows. There is also another method, in which the blood is supplied to the capillary bed, which is via the collaterals.

- A blockage in the right internal carotid does not necessarily cause a loss of blood supply to the brain.

- The following sequence traces the flow of arterial blood to the left parietal and temporal lobes of the brain. Tell which artery is missing: Blood leaves the heart and passes through the aorta, the left common carotid artery, and the middle cerebral artery. (a) vertebral, (b) brachiocephalic, (c) internal carotid, (d) basilar.arrow_forwardIdentify the incorrect statment about blood vessels (A) arteries are carrying a higher blood pressure than veins (B) skeletal muscle can assist veins with the movement of blood (C) crossing your legs is a ish factor for varicose veins (D) veins and arteries have valvesarrow_forwardThe muscle cells of a heart chamber work as a functional syncytium. In terms of heart function this means... A) All the cardiac muscle cells are controlled by one motor neuron, resulting in coordinated contraction. B) All the cardiac muscle cells are electrically connected by gap junctions, resulting in coordinated contraction. C) All the cardiac muscle cells are stimulated to contract by hormone release, resulting in near-coordinated contraction. D) All the cardiac muscle cells contract independently of each other (fibrillation).arrow_forward

Based on your understanding of body organization, is there evidence to support her claim? (a) Yes, without red blood cells, the heart wouldn’t be able to deliver oxygen to other organs (b) somewhat, because the heart is constructed from specialized tissues, such as muscle tissue, that help it to function but the cells are no different than other body cells (c) no, this in inaccurate because it is the brain, not the heart that help the other organs in the body to function (d) No, because the cells in the heart are not specialized compared with other organs in the bodyarrow_forwardComplete the following statements: The membrane on the surface of the heart is called the ......................arrow_forward
