Which of the following shows the pathway a blood cell in systemic circulation would take?

Use the word bank below to complete the following statements: media vasomotion smooth intima striated externa endothelial cells fenestrated discontinuous capillaries elastin Arteries and veins have similar histology, each having 3 shared tissue layers. Tunica is the innermost layer made of a single layer of and a basement membrane. This layer lines the lumen and comes in direct contact with blood. Tunica is comprised of muscle and stretchy fibers. A primary function of this layer is regulating blood flow through The outer surface of arteries and veins is covered with tunica which is a fibrous connective tissue that both supports the vessel wall and anchors the vessel in the body. Unlike arteries and veins, only have tunica intima. These thin-walled vessels are the only vessels capable of gas and nutrient exchange with tissues. capillaries in the kidney and intestines contain a lot of filtration pores to enhance the passage of substances across the capillary wall. capillaries in the…

is there a reason why there is fatty tissue on the heart compared to just connective tissue?

Which of the following statements best describes the function of the pulmonary arteries or veins?     Pulmonary arteries carry deoxygenated blood from the right ventricle of the heart to the lungs.     Pulmonary arteries carry deoxygenated blood to the right atrium of the heart from the lungs.     Pulmonary veins carry deoxygenated blood from the lungs to the left atrium of the heart.     Pulmonary veins carry oxygenated blood from the lungs to the right atrium of the heart.

When human tissue, such as skin or a blood vessel, is torn or cut, the cells in the damaged region secrete a signal that activates specialized blood cells called platelets in the vicinity. As the platelets come in contact with one another, they begin to form a clot and release ad- ditional chemical signals to attract more platelets as well as other clotting factors until the bleeding is stopped. Which of the following correctly describes the feedback mechanism illustrated by the acti- vation of the platelets? A It is an example of positive feedback because the initial activation of the platelets causes the activation of additional platelets. B с D It is an example of negative feedback because the initial activation of the platelets is caused by a harmful stimulus. It is an example of positive feedback because the ultimate result of initial platelet activa- tion causes the bleeding to stop. It is an example of negative feedback because the initial activation of the platelets causes the…
