H EARTS AND CIRCULATORY SYSTEMS
C LOSED AND OPEN CIRCULATORY SYSTEMS
NORMA HUMANHEARTCIRCULATI BLOO IRED.
Major advantages: closed and high pressure and small diameter blood vessels. The open circulatory system doesn’t flow
through the fluids and known as “hemolymph”
The hemolyph will collect the extracellular blood. The mammalian blood is red when it’s oxygenated, but amphibians have blue.
Bright blue when it’s oxygenated.
T HE ADULT HUMAN MAMMA HEART AND CIRCULATORY SYSTEM
Similar to bird hearts. 4 chambers. They pump to the Pulmonary Artery to get oxygenated.
The Aorta is the major blood vessel. Right to Left.
This is a low pressure circuit compared to the earlier one.
Low Pressure in pulmonary because the blood vessels might burst and lung tissue damage.
Artery – DEoxygenated (AWAY FROM THE HEART)
Veins – Oxygenated. (GOES IN TO THE HERT)

T HE HUMAN FETAL HEART
Receives blood from umbilical cord
The fetus aren’t breathing air. It’s strengthening the blood muscles.
The bypasses – formen ovale and ductus arteriosus
Inferiosr vena cava and enters right venacava
It’s bypassing right ventrical and lung
Some of them goes directly to the aorta
Some of them skips the lungs. C EPHALOPOD HEARTS AND CIRCULATORY SYSTEMS
Invertebrates and intelligent
Their cs is identical to the human systems except theirs look diff and have gills.
Leaves the vessel through EFFERENT
AFFERENT in to the organ
Compare mammalian and squid circulation. The left side are similar. They are pumping oxygenated blood in to the systemic
tissue. Right 9the deoxygenated in to the lungs) in to the gills.
