Concept explainers
a.
To determine: The difference between lymphatic and systemic capillaries.
Introduction: The lymphatic system consists of lymphatic organs, lymphatic ducts, nodes, and vessels. The lymphatic organs are divided into two, the primary lymphoid organs and the secondary lymphoid organs. The primary organs serve as the maturation site for lymphocytes while the secondary organs serve as the differentiation site.
b.
To determine: The difference between the role of the sympathetic and parasympathetic nervous system in blood pressure control.
Introduction: Arterial blood pressure is the pressure applied by the flowing blood inside the arteries of the body. The blood pressure is regulated by several factors that can increase or decrease the blood pressure depending upon the requirement of the body.
c.
To determine: The difference between lymph and blood.
Introduction: The lymphatic system consists of lymphatic organs, lymphatic ducts, nodes, and vessels. The cardiovascular system is made of different components. The heart constitutes the primary organs of the system, and the arteries, veins and blood capillaries form the associated structures of the cardiovascular system.
d.
To determine: The difference between continuous and fenestrated capillaries.
Introduction: The cardiovascular system is made of different components. The heart constitutes the primary organs of the system, and the arteries, veins, and blood capillaries form the associated structures of the cardiovascular system. Among the blood vessels, the pulmonary artery, vein, and aorta form the largest and most important vessel system.
e.
To determine: The difference between hydrostatic pressure and colloid osmotic pressure in systemic capillaries.
Introduction: Hypertension is the condition where the blood pressure of the individual in constantly high due to the increased pressure of blood against the arteries supplying blood to the heart. Hypertension can arise due to narrowing of the lumen of the arteries because of fat deposition.

- Which of the following is not a characteristic of a capillary? a. Fenestrated capillaries allow for larger amounts of materials to be exchanged. b. Sinusoid capillaries are the main type of capillary around the brain. c. Capillaries often are arranged in a capillary bed that is supplied by an arteriole. d. The capillary wall consists of an endothelium and a basement membrane only—there is no subendothelial layer.arrow_forwardMark the following statements as true or false. If a statement is false, correct it to make a true statement a. Arteries are the exchange vessels of the cardiovascular system. b. The tunica intima is composed of a sheet of endothelium, connective tissue, and the internal elastic lamina. c. The tunica media consists of smooth muscle cells innervated by vasomotor nerves. d. Muscular arteries control blood flow at the tissue level. e. Veins have smaller lumens, more elastic fibers, and more smooth muscle than arteries.arrow_forwardSelect the TRUE statement/s: 1 Normal ECG is A S OA) Atrial repolarization occurs during the QRS wave O B) Ventricular repolarization occurs during the T wave OC) P wave precedes atrial relaxation OD) Both A and B OE) Both A and Carrow_forward
- A force that attracts fluid into the capillary from the tissue spaces is Select one: a. venous pressure. b. negative interstitial pressure. c. blood colloid osmotic pressure. d. blood pressure. e. active transport.arrow_forwardPrimary force driving fluid out of the capillary and into interstitial fluid is: a. Interstitial fluid colloid osmotic pressure (ICOP). b. Interstitial fluid hydrostatic pressure (IHP). c. None of the above. d. Blood colloid osmotic pressure(BCOP). e. Capillary Hydrostatic pressure (CHP).arrow_forwardIn the aorta, Select one: a. the resistance to blood flow is high, but velocity of blood flow is low. b. the velocity of blood flow is high, but blood pressure is low. c. velocity is diminished because the total cross-sectional area is small. d. the blood pressure and blood velocity are both high. e. the resistance to blood flow and the blood pressure are both low.arrow_forward
- Which of the following characteristics is unique to capillaries and not to other blood vessels? A. have low blood pressure B. have high blood pressure C. exchange substances (ions, small molecules and water) between blood and tissues D. carry oxygen and carbon dioxide E. connect to the heart and lungsarrow_forwardThe carotid artery of an animal is partially constricted proximal to the carotid sinus during a study. Which of the following cardiovascular changes most likely occurs in response to the constriction? (My opinion is the question is referring to carotid clamping not carotid massage ( carotid massage is usually done on carotid sinus to rapidly lower heart rate)) A. Decreased heart rateB. Decreased systemic arterial pressure C. Decreased venous return to the startD. Increased number of impulses from the carotid sinus E. Increased total peripheral resistance.arrow_forwardA general principle of physiology states that information flow between cells, tissues, and organs is an essential feature of homeostasis and allows for integration of physiological processes. How is this principle demonstrated by the relationship between the circulatory and endocrine systems?arrow_forward
