Specific excretory organs are absent in unicellular organisms belonging to the<u> phylum Porifera.</u>
The organisms of the phylum Porifera are classified under the kingdom Animalia and they lack specific organs in their bodies.
The word "Porifera" refers to pore-bearing organisms.
These animals have loosely organized cells and are found in freshwater marine ecosystems.
On their body, a large number of pores - Ostia - are present which perform various functions such as excretion.
However, respiratory gases and waste materials are exchanged through a diffusion process.
Moreover, in them, reproduction takes place through fragmentation and budding.

Answer:
Heart failure
Explanation:
A client with heart failure has decreased cardiac output caused by the heart's decreased pumping ability. A buildup of fluid occurs, causing dyspnea, dependent edema, hepatomegaly, crackles, and jugular vein distention. A client with pulmonary embolism experiences acute shortness of breath, pleuritic chest pain, hemoptysis, and fever. A client with cardiac tamponade experiences muffled heart sounds, hypotension, and elevated central venous pressure. A client with tension pneumothorax has a deviated trachea and absent breath sounds on the affected side as well as dyspnea and jugular vein distention.
The period of gestation that is characterized by the largest fetal weight gain and fat deposition is the third trimester.
The third trimester is the last phase of gestation. It lasts for weeks 29 to 40, or months 7, 8, and 9.The baby grows, develop, and begins to change position in preparation for birth during this trimester. By the end, a full-term infant usually is between 19 and 21 inches long and between 6 and 9 pounds.
Pregnancy causes major physical and psychological changes in women. Weight gain during the third trimester is a normal part of pregnancy and typically not a reason for concern.
During the third trimester, many women will gain weight quickly. This is because, according to the Office on Women's Health (OWH)Trusted Source, the fetus normally accumulates the most weight during this time.
