Lab Exam #2 part II

systole

contraction correlates to cardiac function and how hard the heart is pumping

pulmonary semilunar valve

controls blood flow from the right ventricle into the pulmonary arteries, which carry blood to your lungs to pick up oxygen

Platelets

involved in hemostasis

Agranulocytes

(1) Lymphocytes B & T (2) Monocytes

Granulocytes

(1) Neutrophils (2) Basophils (3) Eosinophils

bicuspid

(mitral) valve lets oxygen-rich blood from your lungs pass from the left atrium into the left ventricle (left AV valve).

Placenta (Human)

Allantois, Chorion, Yolk Sac

Amnion (Chick)

Amniotic fluid

Amnion (Human)

Amniotic fluid

Erythrocytes

red blood cells; biconcave discs; hemoglobin; oxygen transport

tricuspid valve

regulates blood flow between the right atrium and right ventricle (right AV valve).

diastole

relaxation, correlates to arterial elastic recoil

Leukocytes

white blood cells

Blood Flow

Blood delivers oxygen and nutrients to every cell and removes the carbon dioxide and waste products made by those cells. Blood is carried from your heart to the rest of your body through a complex network of arteries, arterioles, and capillaries. Blood is returned to your heart through venules and veins. The one-way circulatory system carries blood to all parts of your body. This process of blood flow within your body is called circulation. Arteries carry oxygen-rich blood away from your heart, and veins carry oxygen-poor blood back to your heart. In pulmonary circulation, though, the roles are switched. It is the pulmonary artery that brings oxygen-poor blood into your lungs and the pulmonary vein that brings oxygen-rich blood back to your heart

Reproduction and Embryology

Developmental stages--Starfish embryology (compound microscope) Zygote → Morula (solid ball of cells) → → → Blastula with blastocoel →Gastrula with blastopore opening into archenteron (endoderm & ectoderm) →triploblastic

Yolk Sac (Chick)

Food

Chorion (Chick)

Gas exchange

Leukocytes (WBC)

Granulocytes: (1) Neutrophils (2) Basophils (3) Eosinophils Agranulocytes (1) Lymphocytes B & T (2) Monocytes

Endoderm

Lining of digestive/respiratory system

T-wave

Lower heart chambers are resetting electrically and preparing for next contraction

QRS complex

Movement of the electrical impulses through the lower chambers of the heart represents 1) atrial repolarization 2) ventricular depolarization Atrial relax and Ventricular contract

DUBB

Pulmonary and aortic valves close

Heart Valves

The tricuspid valve regulates blood flow between the right atrium and right ventricle (right AV valve). The pulmonary semilunar valve controls blood flow from the right ventricle into the pulmonary arteries, which carry blood to your lungs to pick up oxygen. The bicuspid (mitral) valve lets oxygen-rich blood from your lungs pass from the left atrium into the left ventricle (left AV valve). The aortic semilunar valve opens the way for oxygen-rich blood to pass from the left ventricle into the aorta, your body's largest artery, where it is delivered to the rest of your body.

Allantois (Chick)

Waste storage

terrestrial vertebrate embryological development

Yolk Sac, Amnion, Allantois, Chorion

Mesoderm

circulatory, muscular & skeletal system; connective tissue

Germ Layers

ectoderm, mesoderm, endoderm

P-wave

electrical activity through upper heart chambers, represents atrial depolarization. Atria contracts

The primary germ layers are

embryonic tissues from which all tissues & organs develop

Ectoderm

nervous system & epidermis of skin

aortic semilunar valve

opens the way for oxygen-rich blood to pass from the left ventricle into the aorta, your body's largest artery, where it is delivered to the rest of your body.

LUPP

trsicuspid and bicuspid valves shut and pulmonary arctic valves open

Blood is returned to your heart through

venules and veins.
