endocrine glands.
The ovary releases eggs and hormones
Endocrine System
Molecular Shape is crucial in a living system because it determines most biological molecules recognize and respond to one another. An example would be when signal molecules releases its signal, it releases a unique shape that specifically fits together with the shape of the receptor molecules on the surface of the receiving cell, much as a key fits into a lock.
The Bloodstream
The stomach releases a chemical signal to the brain, which the brain therefore sends it to the nervous system which we feel the so-called "Hungry feeling"
Leydig cells are responsible for the production of testosterone in the testicles

The small intestine. It has villi that absorb nutrients and then transport them to the bloodstream.
the pancreas secretes insulin
Hemoglobin carries the oxygen molecules into the bloodstream.
When a signal is sent out from the nervous system it is caused a release of a neurotransmitter that releases an action potential.
The set of glands that regulate the activities of certain organs is called the endocrine system. The endocrine system releases chemical products into the bloodstream.
The digestive system prepares food for the bloodstream. The digestive system absorbs food particles and nutrients pass through this system to the bloodstream.
circulatory system
A bloodstream is the flow of blood through the circulatory system of an animal.
So that large, insoluble molecules of food can be broken down into smaller, soluble ones which can then be absorbed into the bloodstream for use by all the cells in the body.
the system releases 100 J of heat and does 100 J of work. just got the question wrong ;-; here's the answer for the homies
