To review:
The difference between an open and closed circulatory system and the reason behind the inability of humans to function with an open circulatory system.
Introduction:
Different organisms possess different kinds of circulatory systems, which have evolved into two different types of the circulatory systems, which are closed and open circulatory system. Open circulatory system is one where body tissues and organs are surrounded by a fluid called hemolymph. This type of circulatory system is mainly found in invertebrates except for earthworm. The closed circulatory system has blood vessels. These blood vessels run transversely through the body and transport oxygen and blood to different organs.

- In what 2 ways is an insect's circulatory system different from a vertebrate's circulatory system? (choose 2 answers) Question 14 options: The insect has closed circulatory system. Insects have a tracheal system that delivers oxygen to it's cells directly so it is not associated with the circulatory system. Insects have a tracheal system that delivers oxygen to it's circulatory system. The insect has an open circulatory system instead of one that is closed (as in vertebrates). This means that the circulatory fluid of vertebrates moves much faster than that of insects.arrow_forwardWhat is the function of the circulatory system in the human body, and how does it work to maintain homeostasis?arrow_forwardnote whether the statements below are consistent with an open or closed circulatory system. The circulating fluid flows in one direction (unidirectionally) through a circulatory loop. The circulating fluid is called hemolymph. Ostia are pores in the heart, important for circulatory function. The circulating fluid is called blood. The circulating fluid remains in vessels as it moves throughout the organism. Is the more efficient type of circulatory system.arrow_forward
- What is the main purpose of the circulatory system? move blood throughout the body move lymphatic fluid from the tissue to the heart digest food move blood and lymph throughout the bodyarrow_forwardVertebrates, such as humans, have a(n) pathway. pulmonary circulatory lungs The heart pumps blood to the tissues through the circuit. systemic terrestrial The heart pumps blood to the lungs through the circuit. gills one-circuit This type of circulatory pathway is seen in organisms that utilize to breathe air. two-circuitarrow_forwardThree circulatory systems of vertebrates are represented in the following diagram. Identify to which group of animals each circulatory system belongs and mention the reasons for considering them as such. ↑ Capilares de las branquias Aorta Capilares sanguíneos ↓ Capilares pulmonares Aorta Capilares sanguíneos ↓ Capilares pulmonares Aorta Capilares sanguineosarrow_forward
- The three major parts of the circulatory system are the heart, the blood vessels, and the blood. The heart is an organ made up of specialized cells. Which of these functions can the heart perform that individual heart cells cannot? using energy pumping blood growing removing wastearrow_forwardUse this labelled diagram of a human heart & major blood vessels to answer these questions. Which structure is labelled "G"? Aorta • Black arrows indicate direction of blood flow Blue structures contain deoxygenated blood Red structures contain oxygenated blood Cardiac muscle Inferior vena cava Left atrium A- Left ventricle Mitral valve Pulmonary artery Pulmonary valve D- -D Pulmonary veins Right atrium N- Right ventricle M- Superior vena cava G. Tricuspid valve K-arrow_forwardWhich of the following is not a function of the vertebrate circulatory system?a. regulation of body temperatureb. protection against injury, foreign toxins, and microbesc. transportation of materials in the bodyd. All of the above are functions of the circulatory system.arrow_forward
- Some animals use diffusion instead of a circulatory system. Examples include: A. sponges and jellyfish B. flatworms and arthropods C. mollusks and annelids D. birds and jellyfisharrow_forwardBriefly describe the differences among animal circulatory systems. What is an open system versus a closed? What are the anatomical differences among vertebrate hearts?arrow_forwardWhat does the circulatory system form up of?arrow_forward
