What else can I help you with?
The exchange of gases for internal cellular respiration is accomplished by?
The circulatory system
Why circulation takes place in animals and plants?
To exchange gases such as co2 and o2
What carries nutrients and oxygen to an embryo from its mother?
The placenta is the organ that carries nutrients and oxygen to an embryo from its mother. It is formed during pregnancy and serves as the interface between the maternal and fetal circulation, allowing for the exchange of gases, nutrients, and waste products.
What are the three phases of transferring gases between the environment and the cells?
The three phases of transferring gases between the environment and the cells are ventilation (breathing air in and out of the lungs), gas exchange (oxygen and carbon dioxide exchange between the lungs and blood), and circulation (transporting oxygen to the tissues and removing carbon dioxide).
Which process accomplishes the movement of gases illasted by the arrows in the diagram?
The movement of gases in the diagram is accomplished through the process of diffusion. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, leading to equal distribution. In the context of gases, it allows for the exchange of gases across membranes such as in the respiratory system.
What is the capillary and what is it main function?
The capillary is the smallest type of the vessels . it consists only of two epithelial cells. and its main function depends on its permeability . so , it is the main site for exchange of nutrition and gases. from the tissues to the circulation and from circulation to the tissues .
Where in the lungs do you exchange gases?
In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
Where does the exchange of gases occur in the plant?
During the stage of photosynthesis, the exchange of gases occur in the leaves.
What is the atmosphere's role in the exchange of gases on Earth?
The atmosphere plays a key role in the exchange of gases on Earth by regulating the concentrations of oxygen and carbon dioxide. Through processes like photosynthesis and respiration, living organisms interact with the atmosphere to maintain a balance in these gases. Additionally, the atmosphere helps to distribute gases across the planet through atmospheric circulation patterns.
What are two goals of circulation and respiration?
Two goals of circulation are to transport oxygen and nutrients throughout the body and to remove waste products such as carbon dioxide. Respiration aims to exchange gases, taking in oxygen from the environment and releasing carbon dioxide produced by cells.
How can leafs exchange gases in the absence of light?
Light is necessary for the exchange of gases in plants.æ Light is what instigates photosynthesis and without photosythesis there can be no gas exchange.
In the mammalian fetus where does fetal blood exchenge carbon dioxide for oxygen?
In the mammalian fetus, the exchange of carbon dioxide for oxygen occurs in the placenta. The placenta is a temporary organ that develops during pregnancy to allow for the transfer of gases, nutrients, and wastes between the maternal and fetal bloodstreams. Oxygen from the mother's blood diffuses into the fetal blood, while carbon dioxide from the fetus diffuses into the mother's blood for elimination.
