Cardiovascular Test

Today in class we tested on the cardiovascular system

Homework due Tuesday:
Read Lab 1 Pig Dissection in preparation for beginning pig dissection lab on Tuesday

Blood Vessels

Today in class:
- Read chapter 14 section on blood vessels
- Identify anatomy of arteries, arterioles, capillaries, venules, and veins
- Describe physiologic functions of various blood vessels in body

Homework due Friday:
- 3 labs are due on Friday: Cardiac Cycle, Heart Rate and Blood Pressure, Heart Structure Labs

TEST ON FRIDAY

Heart Dissection

Today in class we:
Worked on sheep heart dissection: identification of external and internal structures, identify blood flow in through vessels and heart chambers.

Homework due Monday:
- heart rate, cardiac cycle and heart anatomy labs

Blood Pressure and Heart Rate Lab

DO NOW:
Define systole and diastole.
Describe or diagram the events of the cardiac cycle

Today in class we:
Reviewed homework
Worked on Cardiac Cycle, Blood Pressure and Heart Rate Labs

Homework:
Label the diagrams for the heart dissection on Thursday - this is your ticket into the dissection!

Cardiac Cycles

Today in class we:
Discussed the electrical and mechanical conductions of the heart:
- Electrical impulses conducted through specialized tissues or nodes from SA node through the AV node, Bundle of His, Left and Right Bundle branches, Purkinje fibers
- Mechanical contraction of the heart, or cardiac cycle, is produced from alternating systole and diastole contractions of the atria and ventricles. This rhythms are influenced by electrical impulses and changes in chamber pressure.

Homework: due Tuesday
Cardiac Review questions handout

Cardiovascular System

Today in class we:
- Developed grade goals for 4th quarter
- Discussed the anatomy of the heart: right and left atria, right and left ventricles, aorta, vena cava, pulmonary trunk.
