There are two main types of circulatory systems in animals: open circulatory systems and closed circulatory systems.

1. Open circulatory system:
In an open circulatory system, blood is pumped into a body cavity called a hemocoel, where it comes into direct contact with the tissues and organs. The blood is not contained within vessels and instead flows freely throughout the body cavity. This type of circulatory system is found in invertebrates such as arthropods and mollusks.

Drawing of an open circulatory system:

2. Closed circulatory system:
In a closed circulatory system, blood is contained within vessels and is pumped by a heart to circulate throughout the body. This type of circulatory system is found in vertebrates, including fish, amphibians, reptiles, birds, and mammals.

Drawing of a closed circulatory system:

1. Open Circulatory System

- Found in invertebrates such as insects, mollusks, and crustaceans
- Blood is not contained within closed vessels
- Blood flows through open sinuses and body cavities
- Blood contains oxygenated and deoxygenated blood
- Exchange of oxygen and carbon dioxide occurs directly with tissues
- Heart pumps blood into the sinuses
- Blood pressure is low

2. Closed Circulatory System

- Found in vertebrates and some invertebrates (e.g., annelids)
- Blood is contained within closed blood vessels
- Blood is separated into oxygenated and deoxygenated blood
- Heart pumps oxygenated blood to the body
- Veins return deoxygenated blood to the heart
- Capillaries allow for exchange of oxygen and carbon dioxide with tissues
- Blood pressure is higher than in open circulatory systems

3. Single-Circulatory System

- Blood passes through the heart only once per circuit
- Deoxygenated blood is pumped from the heart to the lungs for oxygenation
- Oxygenated blood returns to the heart and is pumped to the body
- Found in fish and some amphibians

4. Double-Circulatory System

- Blood passes through the heart twice per circuit
- Deoxygenated blood is pumped from the heart to the lungs for oxygenation
- Oxygenated blood returns to the heart and is pumped to the body
- Deoxygenated blood is then returned to the heart from the body
- Found in reptiles, birds, and mammals

5. Incomplete Double-Circulatory System

- Found in reptiles and some amphibians
- Similar to a double-circulatory system, but some blood is mixed between the pulmonary and systemic circuits
- Mixing of oxygenated and deoxygenated blood occurs in the heart or aorta

6. Complete Double-Circulatory System

- Found in birds and mammals
- Blood is completely separate between the pulmonary and systemic circuits
- No mixing of oxygenated and deoxygenated blood occurs
