Answers

Define: Valve – a Flap of tissue that

separates the atria and ventricles, and prevents blood from flowing backward

Pacemaker - a group of nerve cells in the right atrium that signal the heart muscle to contract

SeptumSeptum – a wall of tissue that separates the right side of the heart from the left side of the heart

The Heart

The heart is a hollow, muscular organ that pumps blood throughout the body.It is located behind the

sternum, inside the rib cageIt is made of cardiac

muscle, which can contract over and over without getting tired

Heart Structure The right side of the heart is completely separated

from the left side by a wall of tissue called the septum

Each side has two compartments, or chambers Atrium (atria = plural) – the upper chamber that

receives blood coming into the heart Ventricle – the lower chamber that pumps blood

out of the heart Flaps of tissue called valves, separate the atria and

ventricles, and prevent blood from flowing backward.

In the right atrium, there is a group of nerve cells known as the pacemaker, that signal the heart muscle to contract

Wednesday’s Quiz List and describe the three functions of the

cardiovascular system Matching definitions – valve, septum,

pacemaker, atrium, ventricle Label the three types of blood vessels Compare and Contrast the structures of

the three blood vessels. Explain how the structures of each blood

vessel are related to their functions.

Blood Vessels – 3 Types Arteries – carry blood away from the heart

Capillaries – tiny vessels (only one cell thick) where materials are exchanged between the blood and the body’s cells

Diffusion – the process by which molecules move from an area of high concentration to an area of low concentration

Veins – carry blood back to the heart

Blood Vessels

The walls of arteries and veins have three layers. The walls of capillaries are only one cell thick.

Getting back…

When blood reaches the veins, the heart has very little effect on it.

Contractions of skeletal muscles next to the veins, squeeze the blood back towards your heart.

Also, large veins in the body have valves to prevent the blood from flowing backwards.

Arteries & Veins

In this photo, you can compare the wall of an artery with the wall of a vein.

Arteries are thick and have 3 layers

Veins also have 3 layers but they are much thinner.

Blood Pressure

Blood pressure - the force blood exerts against the walls of blood vessels

Caused by the contracting of the ventricles

Decreases as it moves away from the heart.

Path of Blood Flow:

On the back of the Heart Structure and Blood Flow Handout, using your handout and page 536 in your book, list the path blood takes through the heart/body/lungs (in order).

Begin and end at the right atrium.

Path of Blood Flow

Right Atrium Right Ventricle Pulmonary Arteries Lungs Pulmonary Veins Left Atrium Left Ventricle Aorta Body Veins from body Right Atrium

On Assignment 34a, put the following in order. Beginning and ending in the Right Atrium. (Just use the letters.)

A. LungsB. Left AtriumC. Right AtriumD. Veins from bodyE. Pulmonary VeinsF. Body

G. Pulmonary G. Pulmonary ArteriesArteriesH. Left VentricleH. Left VentricleI. AortaI. AortaJ. Right VentricleJ. Right VentricleK. Right AtriumK. Right Atrium

Two Loops

Loop 1 - blood travels from the heart to the lungs and then back to the heart.

Loop 2 - blood is pumped from the heart throughout the body and then returns to the heart.

Learning Goal:Students will understand that blood is a specialized

fluid that has four main components. Each component has a unique function. Students will apply their understanding of components of blood to discuss how this impacts receiving blood from a donor.

Heading 34: Components of Blood videoClass opener: Using your book, find the 4 components of blood.

What percentage of your blood is plasma? Cells?

Blood

Blood consists of liquid plasma and three kinds of cells—red blood cells, white blood cells, and platelets.

Plasma – the liquid portion of blood – 90% water & 10% glucose/fat /vitamins/minerals

Red Blood Cells – carry oxygen from lungs to body and carbon dioxide away from body, back to lungs

White Blood Cells – find and destroy disease causing organisms

Platelets – fragments of red blood cells that help form blood clots

Learning Goal:Students will understand that blood is a specialized

fluid that has four main components. Each component has a unique function. Students will apply their understanding of components of blood to discuss how this impacts receiving blood from a donor.

Blood Types

Blood types are determined by proteins known as marker molecules that are on RBCs.

Blood type A has the A marker

Blood type B has the B marker

AB has both A & B markers

O has no markers

Plasma contains clumping proteins that don’t recognize RBCs with different markers.

If you have blood type A and get a transfusion of type B blood, your plasma will clump the B blood together.

The markers on your blood determine the type(s) of blood you can safely receive.

Rh Factor

Rh factor is also determined by a marker on the RBCs.

Rh+ means you have the marker

Rh- means you don’t have the marker

Rh- blood will develop Rh clumping factor if it receives Rh+ blood

Reading Graphs:

What does each edge of the graph represent?

The percentage of each blood type found in the United States population

- Blood and Lymph

Interpreting Data:

Rank the four major blood types—A, B, AB, and O—from least common to most common. What is the percentage of each type?

AB (4%), B (11%), A (40%), O (45%)

- Blood and Lymph

Calculating:

According to the graph, what percentage of the population is Rh positive? What percentage is Rh negative?

84%; 16%

- Blood and Lymph

Predicting:

What type of blood can someone who is B negative (blood type B and Rh negative) receive? What percentage of the population does that represent?

O negative or B negative blood; 9%

- Blood and Lymph

Lymphatic System

Sometimes the fluid leaks out of the blood vessels as it travels throughout the body.

The lymphatic system is a network of vein-like vessels that returns the liquid to the bloodstream.

Lymph – fluid that consists of water, glucose, and WBC

Lymph nodes – filter lymph, trapping bacteria and other disease causing organisms

Prime Time:

Using your textbook, read pages 548 – 550. Start at “Blood Types” and stop at “The Lymphatic System.”

On a clean sheet of paper with heading #16, answer questions 1-4 on the top pf page 550.
