SiSTEMa Cardiovascular

Ir regularmente ao médico contribui para o bom funcionamento do sistema cardiovascular, pois permite a detecção precoce de possíveis problemas e a adoção de medidas preventivas. Durante as consultas médicas, é possível realizar exames de rotina, como a medição da pressão arterial e a análise dos níveis de colesterol, que ajudam a monitorar a saúde cardiovascular. Além disso, o médico pode orientar sobre a adoção de hábitos saudáveis, como a prática regular de exercícios físicos e uma alimentação equilibrada, que são fundamentais para a manutenção da saúde do coração e dos vasos sanguíneos.

The correct answer is pulmões because they are not a part of the cardiovascular system. The cardiovascular system consists of the heart, blood vessels (including veins and arteries), and blood. The lungs, on the other hand, are a part of the respiratory system and are responsible for the exchange of gases, such as oxygen and carbon dioxide, in the body.

An equilibrated diet is not a risk factor for cardiovascular diseases. This means that having a balanced and healthy diet does not contribute to the development of cardiovascular diseases. On the other hand, sedentarism, smoking, and hypertension are all risk factors for cardiovascular diseases. Sedentarism refers to a lack of physical activity, which can lead to weight gain and other health issues. Smoking damages blood vessels and increases the risk of heart disease. Hypertension, or high blood pressure, puts strain on the heart and blood vessels, increasing the risk of cardiovascular diseases.

The correct answer is dióxido de carbono. In the venous blood, there is a higher concentration of carbon dioxide compared to arterial blood. This is because carbon dioxide is produced as a waste product of cellular respiration and is transported back to the lungs through the veins to be exhaled. In contrast, oxygen is picked up by the red blood cells in the lungs and transported to the body tissues through the arteries, resulting in a higher concentration of oxygen in arterial blood. Nitrogen and methane are not normally present in significant amounts in the blood.

Capilares sanguíneos têm as paredes mais finas entre os vasos sanguíneos. Isso permite que os capilares realizem trocas de nutrientes, oxigênio e resíduos com os tecidos do corpo. As artérias têm paredes mais espessas e elásticas para suportar a pressão do sangue bombeado pelo coração. As veias têm paredes mais finas que as artérias, mas ainda mais grossas que os capilares, e são responsáveis por transportar o sangue de volta ao coração. As arteríolas são vasos sanguíneos menores que se ramificam a partir das artérias e ajudam a regular o fluxo sanguíneo para os capilares.

The correct answer is "miocárdio." Miocárdio refers to the cardiac muscle, which is the muscular tissue that makes up the walls of the heart. This muscle is responsible for the contraction and pumping action of the heart, allowing it to circulate blood throughout the body. The other options, coração (heart), pericárdio (pericardium), and endocárdio (endocardium), are not specific to the muscle tissue of the heart.

During pulmonary circulation, the blood leaves the right ventricle of the heart and is pumped into the pulmonary artery. From there, it is carried to the lungs where it picks up oxygen and gets rid of carbon dioxide. Therefore, the correct answer is that the blood leaves the right ventricle through the pulmonary artery.

The correct answer is "O plasma" because plasma is not a cellular component of the blood. It is the liquid portion of the blood that carries nutrients, hormones, and waste products throughout the body.

In the case of a victim breathing with a heartbeat and no suspicion of spinal injury, the correct action is to place the victim in a lateral safety position. This position helps to maintain an open airway and prevent choking or aspiration of fluids. It also helps to protect the victim from further harm and allows for easier monitoring of their condition until medical help arrives.

The correct answer is diástole auricular. The cardiac cycle consists of both systole and diastole phases. During diástole auricular, the atria relax and fill with blood, preparing for the next contraction. This phase is followed by sístole auricular, where the atria contract to push blood into the ventricles. Then, sístole ventricular occurs, where the ventricles contract and pump blood out of the heart. Finally, diástole geral occurs, where both the atria and ventricles relax and fill with blood again. Therefore, diástole auricular is the phase that does not belong in the cardiac cycle.

The correct answer is "transportar o oxigénio e algum dióxido de carbono." Hemácias, também conhecidas como glóbulos vermelhos, são células do sangue responsáveis pelo transporte de oxigênio dos pulmões para os tecidos do corpo e do dióxido de carbono dos tecidos para os pulmões, onde é eliminado. Essa função é desempenhada pela hemoglobina, uma proteína presente nas hemácias, que se liga ao oxigênio nos pulmões e o libera nos tecidos, enquanto carrega o dióxido de carbono de volta para os pulmões.

The correct answer is "que indicam o número de glóbulos." This means that reference values indicate the number of blood cells.
