The blood vessels carry nourishment to the fetus. It also assists in the male process that cause their hormones to grow.
Circulatory
the circulatory system
Steroid affect every system in the body. For instance, they affect the immune system by decreasing inflammation, the reproductive system by changing the balance of hormones, and the stomach by affecting its lining.
No, mammals have a closed circulatory system as the system consists of veins and arteries, that carry blood through them. Unlike an open circulatory system which also has a heart, but the blood is free flowing throughout the body. For example when you kill an insect, it is like popping a sack filled with blood, which is exactly what insects with open circulatory systems are.
The cadiovascular system, sometimes called the circulatory system when it includes the lymphatic system.
excretory and circulatory
male: reproductive and excretory female: excretory
* circulatory system * digestive system * endocrine system * integumentary system * immune system * muscular system * nervous system * reproductive system * respiratory system There are actually more than nine. The ones not mentioned are: * skeletal system * excretory(urinary) system
The reproductive system works closely with the endocrine, nervous, and integumentary systems. The circulatory system is also important. The male reproductive system is closely tied with the urinary system as well.
Cockroaches do have circulatory systems, they are are open circulatory systems
The circulatory system affects the other body systems because the circulatory system gives oxygen to the other system. Without the circulatory system the other systems would not work.
a circulatory system
There are many different body systems for example, "Muscular, skeletal, reproductive, respiratory, and integumentary". The systems of the human body are the Digestive, Respiratory, Circulatory, Muscular, Skeletal, Reproductive, Nervous, and Excretory.
Reproductive System, Nervous System, Digestive System, Circulatory System Doesn't it also include the Excretory system, the Muscular System, and Endocrine system?
Circulatory, Digestive, Endocrine, Integumentary, Lymphatic, Muscular, Nervous, Reproductive, Respiratory, Skeletal, and Urinary you will get 12 systems if you separate the male and female reproductive system, and 13 if you include the sensory system as its own system
