Stages of the cardiac cycle [edit] AV Semilunar Status of ventricles and atria valves* valves† • Atria contract and pump blood 1. Atrial Systole open closed • Ventricles, already partially filled from phase 5, receive last ~30% of blood, for a final resting volume of approximately 130mL. • Ventricles begin to contract. Ventricular muscle initially shortens 2. Isovolumetric closed closed only a little, but intraventricular pressure rises sharply Contraction • Ventricular volume unchanged • Pressures in left and right Ventricle exceed pressures in Aorta (80mmHg) and Pulmonary Artery (10mmHg). Ejection is rapid at 3. Ventricular first, slowing down as systole progresses. closed open Ejection • Amount ejected each ventricle per stroke at rest is 70-90mL. Approximately 50mL of blood remains in each ventricle at the end of systole • Valves close as Ventricles relax and pressure within Ventricles 4. Isovolumetric drops below 120mmHg. This ends once Ventricular Pressure falls closed closed Relaxation below Atrial pressure and AV valves open • pump blood to rest of body • ventricles relaxed • ventricles passively fill with approximately 70% of their final 5. Ventricular open closed volume. As the ventricles fill, rate of filling decreases and the AV Filling valves drift towards closing • atria expand and are filling * AV (atrioventricular) valves: 1) mitral valve – between the left atrium and the left ventricle 2) tricuspid valve – between the right atrium and the right ventricle † Semilunar valves: 1) aortic valve – between the left ventricle and the aorta 2) pulmonic valve – between the right ventricle and the pulmonary artery ADDITIONAL PRACTICE

KEY Cardiovascular Study Guide

Isengard-Anatomy CP

Learning Objectives:

 RBC & WBC Formation (Red Blood Cell terms, reticulocyte, granulocyte, myeloid stem cells)

 Red blood cells are formed with reticulocytes. They originate in bone marrow and will be recycled in the spleen.

 Various hormones are required for RBC formation. Erythropoeitin is one of the main hormones.

 -White Blood Cells are categorized as granulocytes or agranulocytes (possessing no granules).  Most WBCs arise from myeloid stem cells with the exception of the lymphocytes.

 Granulocytes include neutrophils, eosinophils & basophils

 Agranulocytes are the monocytes ,lymphocytes

 Steps of Hemostasis (Blood Stoppage)

1) Vascular Spasms (Serotonin Secretion)

2) Platelet Plug- Prothrombin Activator-forms plug

3) Fibrinogen will generate fibrin ( a tissue that will cover the injury)

 Steps of Clotting Cascade (Diagram these steps below) Prothrombin, Thrombin, etc.

http://memorize.com/blood-human-anat-and-phys-7th-ed-marieb

Name the hormones responsible for producing:

 Erythrocytes-Erythropoeitin

 Leukocytes-Interleukins &Colony Stimulating Factors (CSFs)

 Platelets-Thrombopoeitin

Distinguish the differences between antibodies and antigens.

Antigens are markers that identify the blood type as a person’s own(for example, Type A blood would possess A antigens.

Antibodies are generated as an immune response to protect blood from foreign agents. For example,Type A blood would produce B antibodies and vice versa. Identify these in the table below

List the steps of the cardiac cycle

1. Location and Size Use the letters to label the heart image above

a. Atria (2) g. (AV) Valves (What are their names & how many b. Ventricles (2) flaps are in each one?) c. Sup. and Inf. Bicuspid-2 Left / Tricuspid 3 Vena flaps right

d. Pulmonary Trunk

e. Pulmonary Veins

f. Aorta h. Semilunar Valves- pulmonary leads to lungs/ aortic leads to aorta (main artery of the body).

5. Cardiac Circulation- blood flows from the atria to the ventricles. Valves do not allow backflow.

B. Physiology of the Heart (pp. 368–374)

1. Intrinsic Conduction System of the Heart: Setting the Basic Rhythm

a. Intrinsic Conduction System-

Electrical impulses through nerve signals control heart rate.

SA Node & AV node signal contraction in a healthy heart.

ii. Ischemia-Dead heart tissue usually resulting from a heart attack

iii. Fibrillation Heart rhythms become out of sync (Defibrillators are used to restart the heart impulses).

2. Cardiac Cycle and Heart Sounds- Lub Dub Noises are generated when blood exits the atria (Lub) and then passes through the through the semilunar valves AORTA- & PULMONARY (Dub).

Murmurs-Additional sounds from the lub dub rhythm may indicate backflow from one of the AV valves that close improperly.

Calculating Cardiac Output (CO) CO= HR (Heartrate)X SV (Amount of blood pumped through the heart in one time).

a. Regulation of Stroke Volume (SV) AV and Semilunar Valves typically control stroke volume.

b. Factors Modifying Basic Heart Rate (HR)-Stressful situations can lead to an increase in angiotension, vasoconstrictors, and other hormones that would speed up or slow down the heart rate to accommodate to one’s environment.

II. BLOOD VESSELS (pp. 374–395)

A. Microscopic Anatomy of Blood Vessels (pp. 374–377)

Tunica Media (composed of involuntary smooth muscle)

Tunica Externa-Strong outer layer of vessels

a. Arterial Supply of the Brain and the Circle of Willis

(Pictured to the right; is responsible for circulating blood through the brain from the central nervous system to the peripheral nervous system).

Fetal Circulation

This process shuttles blood from the mother to the developing fetus with several important steps.

 The placenta (site of nourishment-similar to a yolk sac) will transfer blood flow to the baby’s developing liver.

 All oxygen poor blood will then travel to the baby’s heart through the DUCTUS VENOSUS and then pass through the heart. DUCTUS ARTERIOSUS delivers blood back to the fetus after maternal circulation.  One important step in this process is that blood flow does not enter pulmonary circulation but rather bypasses it through the FORAMEN OVALE ( a hole between the two atria).

 This important step happens because the baby’s lungs are NOT fully functional and therefore they do not require pulmonary circulation.

c. Hepatic Portal Circulation

 This process is important for digestion. It delivers necessary nutrients from digestive tract to the blood for circulation throughout the body.

 Hepatic refers to the liver (Hepatitis-Inflammation of the Liver)
