Blood Circulation and Transportation
Invertebrate
Cnidarians & Flatworms
2 types
open circulatory system
Haemolymph
arthropods
molluscs
closed circulatory system
Blood
earthworms
Differences open & closed
Function of Circulatory System
transport heat & transmit force in body
pick up wastes and excreted from body
transport oxygen and nutrients
gas exchange and nutrient-for-waste exchange
Vertebrate
Single-loop
Single atrium & Single ventricle
Two-circuit
Two atria & Single ventricle
complete separation
Systemic circuit
Pulmonary circuit
Created by Laurie Ali & Reynold Ramsy
Circulation
moving fluid in body
provide rapid mass transport
over distance where diffusion is inadequate
Lymphatic system & functions
Lymphokinetic Motion and Pressure Gradient
Highest pressure
Blood capillaries
Interstitial fluid
Lymph capillaries
Lymph veins
Lymph Ducts
Large circulatory veins

Lymphatic organ
Primary
Thymus
Bone marrow
Production and selection of lymphosite
Secondary
site of lymphocytes activation by antigen
Lymph nodes
Spleen
Functions:
Fat absorption and transportation
Immunological defense
Fluid balance
Lymphatic disorder:
Lymphedema
Elephantiasis
Lymphatic filariasis
Mammalian cardiovascular system
Heart (cardio)
heart valves
Atrioventricular valve
Semilunar valve
rhythmic heartbeat
cardiac cycle
phases
ventricles contract
all chambers rest
atria contract
Systole (contraction)
Diastole (relaxation)
70 times/minute
each side- 2 chambers
blood vessels (vascular)
Capillaries
permit exchange of material with tissues
Veins (and venules)
return blood from the capillaries to the heart
Arteries (and arterioles)
carry blood away from the heart to the capillaries
Cardiovascular diesease
stroke
a small cranial arteriole bursts or is blocked by an embolus
Heart attack
coronary artery is completely blocked
prevention
Don't
smoke
Abuse drug
gain wwight
Do's
Eat healthy
check cholestreol
excercise
Blood pressure
measured on the brachial artery of the upper arm
Systolic pressure
ventricular systole
Diastolic pressure
ventricular diastole
