Introduction:
Neck is an anatomical structure of the body that connects the head with the trunk to provide the mobility and movement of the head.

Introduction:
Skull is a bone framework that covers the brain and provides support to the structureof the face of all the vertebrates.
(e)
To determine:
The arteries that a red blood cell would encounter in the tip of the fingers of the left hand if it started in the left ventricle.
Introduction:
A finger is a limb, and an organ of manipulation and sensation occurs in the hands of humans and all the living organisms.
(f)
To determine:
The arteries that a red blood cell would encounter in the Anterior compartment of the leg if it started in the left ventricle.
Introduction:
Legs are the anatomical structure that is responsible for weight-bearing and locomotion.
(g)
To determine:
The arteries that a red blood cell would encounter in the liver if it started in the left ventricle.
Introduction:
Liver is an organ that used to detoxifies various metabolites, synthesizes proteins, and produce biochemical products for digestion in the body.
(h)
To determine:
The arteries that a red blood cell would encounter in the small intestine if it started in the left ventricle.
Introduction:
Small intestine is an organ present in the gastrointestinal tract where absorption of nutrients and minerals takes place.
(i)
To determine:
The arteries that a red blood cell would encounter in the urinary bladder if started in the left ventricle.
Introduction:
Urinary bladder is a hollow muscular organ that collects and stored urine from the kidney. In humans, the urinary bladder can hold 300-500 mL of urine.

SEELEY'S ANATOMY+PHYSIOLOGY
- All the blood that passes through the aorta, except the blood that flowsinto the coronary vessels, returns to the heart through the venae cavae.(Hint: The diameter of the aorta is 26 mm, and the diameter of avena cava is 32 mm.) Explain why the resistance to blood flow in theaorta is greater than the resistance to blood flow in the venae cavae.Because the resistances are different, explain why blood flow can bethe same.arrow_forwardThe carotid arteries are the major blood vessels that are in the neck and supply blood to the brain, neck, and 2. Using a textbook as necessary, list the major arteries through these pathways in a human: a. Blood as it travels from the left ventricle to the arcuate artery of the foot. b. Blood as it travels from the brachiocephalic trunk to the right superficial palmar arch. BIUE ET T,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
- Arteries differ from veins in their thicker ____ and ____. a. squamous epithelium . . . outer layer b. endothelium . . . connections to precapillary sphincters c. smooth muscle . . . one-way valves d. outer connective tissue . . . smooth musclearrow_forwardWhich of the following best describes an artery? Select one: a. thin-walled, and supplied with valves and nerves b. thin-walled, elastic and supplied with nerves c. thick-walled, elastic and supplied with nerves d. thick-walled, elastic and supplied with valvesarrow_forwardThe largest cross-sectional area in the total circulation and lowest blood flow velocity is found in: A. The Aorta. B. The capillaries. C. The Vena Cava. D. The small arteries. E. The Pulmonary Vein.arrow_forward
- Which of the choices below best describes the systemic circulation of blood?a. The flow of blood into the right atrium and eventually out of the left ventricle.b. The movement of blood from the pulmonary trunk, through capillaries into the pulmonary veins.c. The movement of blood into the coronary arteries, through capillaries into the coronary sinus.d. The movement of blood from the aorta, through arteries and capillaries and then eventually to the vena cavae.arrow_forwardThe innermost serous membrane attached to the heart muscle is called the: a. visceral pericardium. b. visceral peritoneum. c. visceral pleura. d. parietal pericardiumarrow_forwardDuring a cardiac angiogram, it is discovered that a 58-year-old patient has moderate stenosis of the left circumflex artery. Which chamber of the heart would be impacted by this blockage?arrow_forward
- Match the following types of arteries to their descriptions ? provides the greatest resistance to blood flow ? "has more smooth muscle, but less elastin, and delivers blood to specific organs" ? includes the aorta and brachiocephalic arteries A. Muscular Arteries B. Arterioles C. Elastic Arteriesarrow_forwardMark the following statements as true or false. If a statement is false, correct it to make a true statement. a. Arterioles reflexively dilate when blood pressure increases. b. Increased concentrations of carbon dioxide and hydrogen ions and a decreased concentration of oxygen in the interstitial fluid cause local arteriolar constriction. c. Tissue perfusion to the heart decreases during systole and increases during diastole. d. The increase in tissue perfusion in skeletal muscle that occurs during exercise is known as hyperemia. e. The sympathetic nervous system causes vasodilation in the skin when body temperature decrearrow_forwardYou have a young woman on your ward who is awaiting heart surgery. She is keen to know about the structure and function of the heart and asks you to explain the flow of blood through the heart from start to finish. She wants to hear anatomical names and learn about physiological processes ejecting blood from her heart, your response will help keep her distracted from thinking about her upcoming operation. a. Describe the flow of blood through the heart, naming each of the vessels bringing and taking blood to and from the heart. Include chambers of the heart and name structures in the correct sequence along the blood's pathway through the heart - begin with blood returning to the heart from the body and end with blood being ejected into the systemic circulation. Include the names of the valves and identify which valves are open and closed during each cardiac cycle. Describe, using terms like diastole and systole, the changes in ventricular pressure during one cardiac cycle and…arrow_forward
